I had a low mile white HR 186s Premier auto about 10yrs ago that was a showroom display car for a Holden dealership when new. Had most Nasco accesories but one I have never seen before or since. It had a radio fader that sat below the dash. It had it's own mock wood facia that matched the rest of the car. This was an original unmessed with car and was not an after market fitment. Anyone seen this option before.
